How long must an operator wait after filing a notification with the Utilities Technology Council (UTC) before operating on the 2200-meter or 630-meter band?
The correct answer is B: Operators may operate after 30 days, providing they have not been told that their station is within 1 kilometer of PLC systems using those frequencies. How long an operator must wait after filing a notification with the Utilities Technology Council (UTC) before operating on the 2200-meter or 630-meter band is that operators may operate after 30 days, providing they have not been told that their station is within 1 kilometer of PLC systems using those frequencies. There's a 30-day waiting period unless notified of proximity to PLC systems. For amateur radio operators, this is important for low-band operation. Understanding this helps ensure legal operation.
Exam Tip
UTC notification wait time = 30 days unless notified of PLC proximity. Think 'U'TC 'N'otification = 'U'p to '3'0 days. Operators may operate after 30 days, providing they haven't been told their station is within 1 km of PLC systems. Not approval required, not test signal, not immediate - just 30 days unless notified.

Real-World Application
You file a notification with UTC for 630-meter operation. You may operate after 30 days, providing you haven't been told that your station is within 1 kilometer of PLC (Power Line Carrier) systems using those frequencies. If UTC notifies you of PLC proximity, you must coordinate. Otherwise, 30 days is the waiting period. This is the requirement.

Why Other Options Are Wrong
Option A: Incorrect. Operators don't have to wait for approval - they can operate after 30 days unless notified. Approval isn't required.
Option C: Incorrect. Test signal coordination isn't required - operators can operate after 30 days unless notified. Test signal isn't required.
Option D: Incorrect. Operations can't commence immediately - there's a 30-day waiting period. Immediate operation isn't allowed.
